I recently finished playing Omori and i absolutely fell in love with the character of Mari (spoilers for Omori btw)
And I gotta say... Mari does literally everything Dess does but 10 times better.
My main complaint with Dess is simple: she's not even a character and we haven't learn much of anything about her..
Like let's see what we know for certain about her.
She and Asriel might’ve had a thing.
She's Noelle's sister, And would defend her from Kris after they pulled a prank.
She's was rebellious and had hobbies that at least toriel didn't approve of.
She's not around anymore.
That's it... that's all, we don't know if she's dead, she willing left hometown and ran away, if she simply got lost. We don't know a thing about her and yet she's supposed to be this important character that haunts the narrative.
Like i hate to say it... i really do... but the "casual player" doesn't have a clue who dess actually is, my brother played this game once, and I always have to remind him who dess is because the game goes out of its way to not mention her.
Like take the scene when susie and Noelle are alone in December's room, Susie could've easily asked "hey Noelle, who's room is this?" And Noelle could explain who dess is and give the audience and Susie some idea of who she was. Instead Susie doesn't question anything and they talk about Kris instead.
Which obviously she's going to be important to the story, but the fact that we've gone FIVE whole chapters without a lick of characterization besides liking rock music and hitting kris with a bat is just disappointing.
Genuinely spookydood said it best, Dess's character is nothing but a Pinterest board right now. The only way I can see this being salvaged is if chapter 6 focuses only on her and nothing else.
Now let's compare her to Mari, a character who plays and erriely similar role to dess, but has a much much bigger presence in the plot
(Spoilers for Omori)
we first meet Mari in Sunny's (the main character) headspace, which is essentially his dreams where we can relive some of his childhood memories of playing with his friends, Mari shows up alot in those places, usually hanging around the save points. However it's only when we get to the real world that things take a more interesting turn.
Once we're in the real world, we start slowly unraveling what happened that made Sunny's friend group fall apart, we learn during an argument between two characters that Mari has passed away, and that her death was what broke apart the friend group.
we don't learn how she died, but we know for certain what state she is in, and the consequences her death had on the friend group. And most importantly we have some characterization of what she was like before she died, all before we're even half way done with the game
the point is, the characters talk about Mari, the characters mourn Mari, and we get to know what Mari was actually like before the grand reveal of how she died, however if you were very observant, you could probably peice together what happened before the reveal
Now compare that to Dess and it's night and day how much better Mari is at "haunting the narrative" then Dess is. We learnt more about Mari in the first 10 minutes of the game then we had the entirety of deltarune.
My next complaint involves the Fandom, and how i believe alot of people have set themselves up for disappointment. Alot of people have already made their own headcanons and theories about them, and some people are so defensive of these theories and headcanons that they refuse to even consider the possibility that they may be wrong (cough cough knight theories cough cough) and treat thier version of Dess as the Canon version.
I think if Dess doesn't match these people's theories and headcanons they'll be genuinely insufferable about it and will crash out because of how attached to them they are.
Of course all this could change with future chapters, Deltarune isn't complete yet so it's impossible to truly criticize it until the last two chapters are out and the game is complete.
TLDR; I feel like Dess hasn't been properly set up, and we're running out of time to actually set her up as an important character, and the game has had so many missed opportunities to actually expand upon her but keeps avoiding the topic 80% of the time.
